Explanation of Solution
Given information: The rate of depreciation of Zita’s computer is 3% per year. The purchasing cost of the computer is $1200.
Calculation:
As per the given problem,
Rate of interest per year( r ) =3%,
Principle ( p ) =$1200.
Depreciation value ( A ) aftern years A =
A =
So, the desired equation for the given situation is A =

Explanation of Solution
Given information:The rate of depreciation of Zita’s computer is 3% per year. The purchasing cost of the computer is $1200.
Calculation:
As per the given problem,
Rate of interest per year( r ) =3%,
Principle amount ( p ) =$1200.
Depreciation value ( A ) after n years=
The value of the computer after 5 yearsis A =
A =
A =$1030.48
The value of the computer after 5 year is $ 1030.48
